Berpikir Kritis (Critical Thinking)• Ennis (1985), berpikir kritis merupakan bagian dari pola
berpikir tingkat tinggi yang bersifat konvergen. Berpikir kritis menggunakan dasar proses berpikir untuk menganalisi argumen dan memunculkan gagasan terhadap tiap-tiap makna dan interpretasi, untuk mengembangkan pola penalaran yang kohesif dan logis, memahami asumsi dan bias yang mendasari tiap-tiap posisi, serta memberikan model presentasi yang dapat dipercaya, ringkas dan meyakinkan.
• Facione (1998), inti berpikir kritis adalah deskripsi yang rinci dari sejumlah karakteristik yang berhubungan, yang meliputi analisis, inferensi, eksplanasi, evaluasi, pengaturan diri, dan interpretasi

Make easy to use
CCK in middle school: “Make the light bulb light”
CCK in high school:
“Explain why the light dims when you turn the heater on”
Adaptable for Variety of Learners

Provide real-time, animated
feedback as students play
Implicitly scaffold inquiry through
design of controls and representations
Make simulations highly interactive
Use accurate, dynamic visual representations
Show the invisible
Provide an intuitive interface,
usable without instructions
Create a game-like environment
Allow actions that would be difficult or impossible
in the real world
Designed to support inquiry learning

Use of PhET sims in class
Lecture/classroomVisual Aid, Demo complement, Interactive Lecture Demos, & Concept tests
Lab and RecitationGroup activity, Exploration &
discoveryHomework
Pre-class assignment – introduce new ideasPost instruction – develop robust
understanding

Ideas for Next steps• Try ideas from teachers
• http://phet.colorado.edu/en/for-teachers/browse-activities
• Use Key Word Search to find a sim, then scroll down for ideas• Watch for Gold Star Inquiry Activities
• Think about your learning goals use Key Word search to find sims
• Search for sims by Topic or Grade level • Read handouts from webinar• Watch iTunes PhET videos

Simulation Extends Lab Concepts
• Qualitative lab: Use the motion probe to graph position and velocity of some motion, also make motions to fit given graphs
• Quantitative lab: Use Moving man to accurately interpret and draw position, velocity and acceleration graphs for common situations and explain reasoning.

Lecture – Interactive Lecture Demos
Demo 4: Sketch position vs time and velocity vs time graphs for when Moving Man: walks steadily towards the tree for 6 seconds,then stands still for 6 seconds, and then towards the house twice as fast as before for 6 seconds.
